I’m doing so well and life is just life :) but what about u how has ur day been going
An example of Algebra structure work is simplify (8-3)+3.
<h3>What is algebraic structure?</h3>
In mathematics, an algebraic structure is known to be a term that is made up of a nonempty set A, a combination of operations on A of finite series and a finite group of identities.
To simply this equation, (8-3)+3.
One has to follow the order of operations using the P.E.M/D.A/S technique, the expression that are in the parenthesis have to be solved first.
2 of 3
(5)+3 = 8
Therefore, the answer is 8

Answer:
x = 21
Explanation:
The two remaining angles must add to 90 degrees since a triangle adds to 180
3x+6 +x = 90
4x+6 =90
4x = 90-6
4x = 84
Divide by 4
4x/4 = 84/4
x = 21
GOLD IN THE SKY - By Alan E. Nourse
We can see in the story that the setting is in a cockpit, in a lab, simulating a landing to Mars because of this paragraph; "Greg twisted around in the cockpit that had been built just big enough to hold him, and shifted his long legs against the brace-webbing, trying to get them comfortable." We can see that Greg Hunter is nervous, "His heart hammered in his throat, and his eyes ached fiercely, but he paid no attention. His finger crept to the air-speed indicator, then to the cut-off switch." The time period we can state is around the 1950s. It implied the first trip to Mars, "He heard the count-down monitor clicking in his ears, and his hands clenched into fists. How far from Mars would he be 10 minutes from now?" In conclusion, the time is believed to be sometime in the 1950s, and the setting is in a lab where Gregory Hunter is going on a trip to mars when something wrong has happened.
